On the Mesh Sweeping page, it mentions this - "This method of meshing complements the free mesher"

What's free mesher?

Please can you post a screen shot? There's a "free mesh type" in the Multizone method, but it could be a translation misunderstanding too.

Can't access Ansys right now but here is the text -

Mesh Sweeping

This method of meshing complements the free mesher. If a body's topology is recognized as sweepable, the body can be meshed very efficiently with hexahedral and wedge elements using this technique. The number of nodes and elements for a swept body is usually much smaller than ones meshed with the free mesher. In addition, the time to create these elements is much smaller.

Workbench will automatically check to see if the body fulfills the topological requirements for sweeping. It will then choose two faces that are topologically on the opposite sides of the body. These faces are called the source and target faces. Workbench will mesh the source face with quadrilateral and triangular elements and then copy that mesh onto the target face. It then generates either hexahedral or wedge elements connecting the two faces and following the exterior topology of the body.

Thanks. I think it's the generic term for all meshes that aren't sweep: ie the unstructured or cutcell/hexcore/poly methods as they're very flexible ("free" from some constraints - a less commonly used definition).
